Let's move work management inside the vdpa_sim core. This way we can easily change how we manage the works, without having to change the devices each time.

v2: - rebased on Linus' tree, commit ae3419fbac84 ("vc_screen: don't clobber return value in vcs_read") - removed `struct task_struct *owner` param (unused for now, maybe ?useful to support cgroups) [Jason] - add unbind_mm callback [Jason] - call the new unbind_mm callback during the release [Jason] - avoid to call bind_mm callback after the reset, since the device ?is not

This series adds support for the use of user virtual addresses in the vDPA simulator devices. The main reason for this change is to lift the pinning of all guest memory. Especially with virtio devices implemented in software. The next step would be to generalize the code in vdpa-sim to allow the implementation of in-kernel software devices. Similar to vhost, but using vDPA so we can reuse the
